Interpretation:

  • Lower volatility = smoother ride
  • Higher Sharpe/Sortino = better risk-adjusted returns
  • Smaller max drawdown = less worst-case pain
  • Beta > 1 = more volatile than S&P 500

Risk metrics use the available common observations, a 4% annual risk-free assumption and SPY as the beta benchmark.

Price Correlation

What this report can and cannot establish

Known overlap: for each shared security, we add the smaller reported fund weight. Reported weights remain in their original scale.

Possible overlap: the upper bound adds only the smaller unreported portion. It is uncertainty, not an estimate that the missing positions actually match.

Prices: returns and risk use adjusted-close observations, so distributions and splits are reflected when supplied by the market-data source.

No recommendation: EigenDex does not assign a winner. Costs, tax treatment, liquidity and mandate should be verified with each issuer before acting.
